Application filed .I 1113: 2d,

To all whom it may concern Be it'known that I, STEPHEN JENCICK, a subject of Austria, residing at the city of Minneapoiis,,in the county of Hennepin and State of Minnesota, have invented a new and useful Motor-Indicating Mechanism, of which the following is a specification.

My invention relates to improvements in systems for indicating the internal condition of internal combustion engines, and has for its objects to accurately indicate the temperature within the crankcase, and about the moving and working parts of'such motors.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure l is a front elevation of the indicating part of my invention, and Fig. 2 is a vertical section of part of my mechanism on the line 1-l, Fig. 1. Similar letters refer to similar parts throughout the several views.

This indicating apparatus may be used upon all internal combustion motors having a circulatingoiling system and is mom accurate and eliicicnt when used in connection with a force-fed oiling system in such motors.

Ports a and I) are suitably connected with the circulating lubricant of the motor by tubes 0 and 0? so that the lubricant from the motor is-constantly circulating through port a, which projects into chamber 8, so that the quantity of circulating lubricant may be more plainly seen, drips to the bottom of chamber c and is conveyed through port Z) to the parts of the motor to be lubricated.

The indicating portion of the mechanism consists of a metal casing 7', which is provided with suitable screw holes for mounting upon the dash board of an automobile or upon any suitable mounting. Glass partition it forms an oil tight chamber a with casing 7 except for parts a and b. Thermometer 2' is positioned in the indicating mechanism with its bulb in chamber c and below port 6 so that the same is completely covered with circulating oil, and with its stem projecting through a suitable aperture in partition k and contained in chamber j, which is formed between case f, partition h and "glass dust cover is. The thermometer may be sealed into the opening in partition Specification of Letters Fatent.

of the motor, Whether the same is used in an automobile, launch or in whatever other manner and which takes the place of the sight iced. now commonly used in internal,

. gases and each of these conditions are more accurately indicated by the carburetor adjustments. by such external conditions as the knocking of the motor, carbon in the exhausted gases, or by the sight feed ,oiler common in such engines.

On the contrary, the mechanism herein described indicates the heat condition within the motor by a circulating medium which is constantly in running contact with the vital and moving parts of the motor and indicates immediately any trouble in the bearings of the'motor', the lubrication of the cylinders or any other real condition of danger.

Any test which relies upon the temperature of the cooling medium or steam or vapor generated by the heat of the motor therefrom, must be conceded to he of little practical value for'it is a demonstrated fact that the ideal temperature condition for motors of this kind is far above that of the boiling point of any liquid cooling" medium in use. Moreover such systems are not applicable to air cooled motors Which are growing daily in popularity. Also a condition wherein the lower part of the circulating system was frozen or clogged and steam Was being generated at the motor would not be as accurately indicated by'a system depending upon the cooling fluid of the Va or above such fluid as bythe system dcscri ed herein.
